QueryResult

Overview

This class is used internally by DA Linq to represent Linq query results while processing them in the LinqDataAdapter or RemoteTable classes.

Please note that you cannot create instances of this class directly, because it is marked as abstract. You can use the EnumerableQueryResult or EnumerableQueryResult classes instead.
